Following Steve Carell's Michael Scott's departure after seven bumbling, fumbling and ultimately lovable seasons, the show is undergoing a series of changes. While a new regional manager has yet to be introduced, joining the cast full time as Katy Bates's replacement as CEO of Sabre -- the company that owns Dunder Mifflin -- will be James Spader, who played a sort of demented Jedi mind trick business man in last season's star-packed finale.
